摘　　要：目的比较高温热塑充填技术与冷牙胶侧方加压充填技术根尖封闭能力;方法收集68颗新鲜离体牙为研究对象,随机分为A组(30颗牙)、B组(30颗牙)、实验阳性组(4颗牙)、实验阴性组(4颗牙),A组采用高温热塑充填技术,B组采用冷牙胶侧方加压充填技术,比较根管充填时间、渗漏现象、封闭性能及顺应性。结果高温热塑充填组根管充填时间(6.48±0.45)min、渗入长度(1.02±0.14)mm明显低于冷牙胶侧方加压充填组;1.5 mm、>100且<250根管1.5mm、≥250根管1.5 mm、3.5 mm截面封闭能力(0.9485±0.0218、0.9504±0.0152、0.9452±0.0147、0.9522±0.0142)、1.5 mm、3.5mm截面顺应性(0.9558±0.0164、0.9722±0.0142)均明显高于冷牙胶侧方充填组(P<0.05)。结论高温热塑充填技术能减少充填时间,增强顺应性,具有良好的封闭效果。Objective To compare the effect between high-temperature thermoplasticized injectable technique and cold lateral condensation on sealing ability.Methods 68 fresh vitro teeth were divided into group A （30 teeth）,group B （30 teeth）,positive group （4 teeth）and negative group （4 teeth）.Group A was given high-temperature thermoplasticized injectable technique,group B was given cold lateral condensation technique.A root canal filling time,leakage phenomenon, sealing ability and compliance were compared.Results Root canal filling time and seeping into length of group A were significantly lower than those of group B,while sealing capacity and compli-ance were significantly higher than those of group B （P 〈0.05）.Conclusion High-temperature thermoplasticized injectable technique can reduce the filling time,increase compliance and perform a good sealing effect on root canal.
